A long time ago, I had a lot of karma, almost a thousand. I was a model citizen for HN. But at some point, I must have posted a controversial opinion, and then HN decided they wanted to cancel me. If it wasn’t for a downvote limit per post, my karma would be below zero by now. Instead it has dwindled and deteriorated slowly over time, trending toward nothing. Nothing I do will move the needle to recover my karma, I’ve simply accepted that someday my karma will be so low that I’ll be shadow banned forever.
Part of this is my own fault, as my posting habits changed to more bitter and cynical tones as a result of knowing that no matter what I say I will accrue inexplicable downvotes, so why spend effort softening my words? But it’s amazing that sometimes a completely mundane post suddenly has -4 downvotes out of nowhere.
I wish I could see a plot of my karma over time, and know the exact point it all went wrong, so that perhaps I could learn and conform a bit better to the popular opinion. Unfortunately I know of no such tool.
